Problems solved by technology

[0002] At present, the existing coal mine tunneling equipment has no support function, and the movement is also crawler-type. The expansion and contraction of the gun head is limited. During the tunneling process, continuous operation cannot be performed. It is often necessary to stop the machine for roof support, which seriously affects the progress of the tunneling. There are also hidden dangers in terms of safety

Embodiment approach

[0033] Because what this machine adopts is a kind of tunneling equipment that the roadheader and hydraulic support are combined, and both roadheader and hydraulic support are the equipment that can already be produced at present. Therefore, in the implementation of the manufacturing process, it is completely productive.

Abstract

A support-type continuous digging machine for coal road or half-coal-and-half-rock road is composed of an improved digging machine and a supporting stack type hydraulic support. Its main body is fixed onto the base of hydraulic support, which is also used as the slide shoe for making the digging machine to run. The front and back hydraulic supports with two hydraulic jacks are used for automatic running. The roof suporting can be performed behind the support while the coal road is continuously dug.

Description

Technical field: [0001] This machine is tunneling equipment for coal mine underground roadway. technical background: [0002] At present, the existing coal mine tunneling equipment has no support function, and the movement is also crawler-type. The expansion and contraction of the gun head is limited. During the tunneling process, continuous operation cannot be performed. It is often necessary to stop the machine for roof support, which seriously affects the progress of the tunneling. There are also hidden dangers in terms of safety. Invention content: [0003] The support type continuous tunneling machine is a tunneling equipment combined with an improved tunneling machine and a hydraulic support, and is suitable for continuous tunneling of coal roadways and semi-coal roadways. It has support function and can walk automatically. The machine works stably and can work continuously without stopping for support. The excavation speed and safety are improved. [0004] This ma...
